The enzyme catalyzing the transfer of glucose from uridine diphosphate glucose to indoxyl yielding the indoxyl glucoside indican was isolated from Baphicacanthus cusia Bremek (Acanthaceae). The indoxyl-uridine diphosphate glucose (UDPG)-glucosyltransferase was purified to homogeneity in six chromatographic steps. The decisive step for the recovery of a homogeneous enzyme was the application of immobilized metal affinity chromatography yielding an 863-fold purified enzyme. From a total of 60 substances tested, in addition to the natural substrate 3-OH-indole (indoxyl), only 4-OH-, 5-OH-, 6-OH-, and 7-OH-indole were accepted as substrates by the glucosyltransferase. However, the latter substrates were metabolized to varying extent. The optimum pH of the enzyme was 8.5, the optimum temperature was 30 degrees C and the isoelectric point was pH 6.5. The M(r) of the enzyme was determined to be 60 +/-2 x 10(3). Indoxyl as substrate yielded a K(m) of 1.2 mM, while a K(m) of 1.7 mM was found for UDPG. << Less
